maybe this code can give you some inspiration to solve at least some

[SailfishDevel] Android Subsystem

[Nils Jeisecke]

Hi list,

Sometimes starting of Android applications does not work. The home
screen shows a panel which says Loading, then the android subsystem
crashes (I guess).
After closing some Sailfish apps, it usually works. A memory problem?

Back Key: When pressing the Back Key and the application does not
handle this the panel on home disappears as if all Android apps were
terminated. On BB10 this simply shows the task switcher.

This plus the general task switching issue renders the whole Android
subsystem currently nearly unusable for me (please read this just as a
bug report - I really want this platform to become successful and
there's already quite a lot which I like about the device).

Re: [SailfishDevel] A new Jolla phone user - after 2 days of use

[Nils Jeisecke]

Oops, sent to early...

- With the white cover and it's ambient active you can hardly read
your network providers's name in the lock screen (not much of an
information loss but it looks rather strange)
- Cannot copy/paste in Mail or in Browser
- Browser can't share links
- Don't like the Browser's look and feel. It is totally out of place
with the rest of the OS.
- Regular disconnects from WLAN
- I had to manually setup the APN for T-Mobile

Don't get me wrong. It's great to have the device but it does wear the
beta tag for a reason. However I love to have double tap to wake-up
back ;-)

But where's the date? Currently calendar has to be open on the home
screen to see that.

Hi,

did anybody manage to create all-day events in the calendar? It shows
existing events as all-day but I can't find a UI for setting that.
